Mine is not a Cossie obviously, but circa 1740kgs on the road, its a damn sight heavier than any Cossie and because of tyres and surface very limited as to how much power can be put down as wheels are spinning throughout the entire 62-124 range. 265/35x18 Westlake E marked tyres, rwd obviously.
2 gearchanges take place for me with this increment. Normal manual clutched H pattern changes. 2-3 and 3-4.

All runs, screenshot from VBox Test Suite enclosed.
